[Git][cmucl/cmucl][master] Reduce maximum heap size for Linux.

Raymond Toy pushed to branch master at cmucl / cmucl Commits: 9e4c9d0a by Raymond Toy at 2016-02-28T21:12:18-08:00 Reduce maximum heap size for Linux. According to the message from Chisheng Huang on cmucl-help, 2016-02-27, 32-bit Ubuntu 11.10 (in VirtualBox) cannot use the full heap space. There's something already allocated at address 0xb7b82000, so limit the max heap to address 0xb7b80000, for a total of 1530 MB instead of 1632 MB. (It would be nice to be able to detect this somehow.) - - - - - 1 changed file: - src/lisp/x86-validate-linux.h Changes: ===================================== src/lisp/x86-validate-linux.h ===================================== --- a/src/lisp/x86-validate-linux.h +++ b/src/lisp/x86-validate-linux.h @@ -22,12 +22,21 @@ * 0x38000000->0x40000000 128M Control stack growing down. * 0x40000000->0x48000000 128M Reserved for shared libraries. * 0x58000000->0x58100000 16M Foreign Linkage Table - * 0x58100000->0xBE000000 1631M Dynamic Space. - * 0xBFFF0000->0xC0000000 Unknown Linux mapping + * 0x58100000->0xB7B00000 1530M Dynamic Space. + * 0xB7B82000->0xC0000000 Unknown Linux mapping, including stack * + * * (Note: 0x58000000 allows us to run on a Linux system on an AMD * x86-64.
